如何将QKeyEvent：：nativeModifier()转换为UINT fsModifiers (用于winapi RegisterHotKey)

Question

我有：

QKeyEvent* event; // I pressed "SHIFT"
modifiers = event->nativeModifiers(); // This is 513 value
RegisterHotKey(..., ..., modifiers, ...); // FAILED because 513 is bad modifier. 
//Right code of "SHIFT" is MOD_SHIFT = 0x0004

如何从QKeyEvent为RegisterHotKey函数获取正确的本机Windows修饰符？

详细信息：

Qt 5.4；QKeyEvent；RegisterHotKey

您可以类似于Qxt库如何转换修饰符：

modifiers = event->nativeModifiers();

quint32 native = 0;
if (modifiers & Qt::ShiftModifier)
    native |= MOD_SHIFT;
if (modifiers & Qt::ControlModifier)
    native |= MOD_CONTROL;
if (modifiers & Qt::AltModifier)
    native |= MOD_ALT;
if (modifiers & Qt::MetaModifier)
    native |= MOD_WIN;

RegisterHotKey(..., ..., native, ...);
